We study the reliability and sensitivity analysis of a system with M operating machines, S warm standbys, and a repairable service station. Failure times and service times of each machine (operating or standby) are assumed to be exponentially distributed. While the service station is working, it is subject to breakdowns according to a Poisson process. When the station breaks down, it requires ...

In industrial systems some components are kept in spare to cope up with the failures of operating components. The failure of these spares too, significantly affects the functioning and outputs of the system. The current paper investigates a semi-Markov model for a redundant system consisting of two identical units and a repair facility. The system starts operating with one unit in operation and...

Volume 87, Number 3 www.aafp.org/afp American Family Physician 217 A 62-year-old nursing home patient presented with dyspnea. He had recently been discharged from the intensive care unit after treatment for urosepsis with multiple organ failure. While in the hospital, he required vasopressors and mechanical ventilation for more than three weeks. After discharge to a skilled nursing facility, th...

Geosynthetic Clay Liners (GCLs) are mainly used to provide watertightness for soils. Their principal function is often fulfilled when construction regulations are implemented. However, when these materials are set in an inclined position, the failure of the whole landfill facility becomes a major concern. Slope stability becomes out significant to be verified; otherwise the principal function o...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...

This paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. The design goal of the control strategy is to minimize fuel consumption and engine-out NOx, HC and CO emissions on a set of diversified driving schedules. Seven facility-specific drive cycles are considered to represent different driving scenarios. For each fa...

OBJECTIVE To review the evolution of technologies in the development of renal replacement therapies. DATA SOURCES Articles and published reviews on renal replacement therapies. SUMMARY OF REVIEW Continuous arterio-venous haemofiltration (CAVH) was the first continuous renal replacement technique capable of overcoming the traditional haemodialysis-related side effects, making possible the tr...

a major reason why many developing nations have not made significant advancement in sustainable development (sd) agenda is the neglect of existing building stock which forms the bulk of built assets. although sustainable development is a universal challenge, it cannot be approached in the same way for all nations, but rather practical response can be defined nationally or locally. this paper re...

BACKGROUND In Tanzania, half of all pregnant women access a health facility for delivery. The proportion receiving skilled care at birth is even lower. In order to reduce maternal mortality and morbidity, the government has set out to increase health facility deliveries by skilled care. The aim of this study was to describe the weaknesses in the provision of acceptable and adequate quality care...
